APPARATUS FOR ATTEMPERATING OR COOLING BEER.

SPECIFICATION forming part of Letters Patent No. 320,618, dated June 23, 1885.

Application filed July 12, 1884. (No model.)

IO appertains to make and use the same.

The invention relates to that class of devices used to coolliquids and to maintain the same at a low uniform temperature, said devices being more especially applicable to the cooling of beer in the beer-vats of breweries.

In lieu of the ordinary swimmer, which, with its charge of c'ooling material, floats upon the surface of the beer, it is the object of the invention to employ a solution of brineor 2O the like as the cooling medium, the same being artificially cooled, as well understood, and being forced to circulate in closed pipes through the liquid to be attempered. rlhe closed pipes being submerged in the heated beer of the vats, enables the cold brine in course of circulation to rapidly abstract the heat and to reduce the beer to a low even temperature. When this desired stage is reached, it is plain that the beer can be easily kept 3o at such point by merely regulating the supply of the cooling agent circulating within the pipes.

The facility and readiness with which the desired uniformity of temperature in the beer may be promptly controlled is an especial point of advantage possessed by this type of mechanism over the old style of swimmer, which it is designed to replace.

My invention consists in the combination, with the vat and with the stationary supply and return pipes for the cooling agent, of the vat-pipe swiveled thereto, said vat-pipe being bent in horizontal coil located near the top of the vat, and being provided with suitable mechanism-such as cord and catches-to hold the pipe in either raised or lowered position. By reason of such organization and location of the parts the more highly-heated portions of the beer are constantly subjected to the cool- A local circulation of the beer within the vat is consequently established, the

hotter portions rising to the surface, andupon being attempered by the cooling agent in the vat-pipe falling again to make room for further portions of the hotter liquid. The vat-pipe being conveniently sustained by the vat itself relieves the swivel-joint from the ,strain and breakage to which it would other- Wise be subject, while the cord and catches enable the workman to quickly adjust and hold the vat-pipe in either raised or lowered position.

In the accompanying drawings, forming part of this specification, like letters of reference denote like parts throughout.

Figure 1 is aviewin elevation of abeer-vat, broken away at the side to show the position of the cooling appliance constituting my invention. Fig. 2 isa View in plan of the vat with the cooling devices attached thereto. Figs. 3 and 4 are detail views in section of the swivel-joints between the vat-pipe and stationary conduits.

The vats A, mounted on usual staging above the iioor of the brewery, are each provided with au inlet-conduit, a, and outlet-conduit a, connecting, respectively, with the supply-pipe 1 and return-pipe 2 of the circulating system. rIhese pipes, as well understood, are in communication with the force-pump, and serve to deliver the cold brine to the individual vatpipes, and to receive the same again after passing therethrough. Said supply and return pipes may be conveniently arranged beneath the staging, so as to be readily accessible, and at the same time to avoid spoiling the beer in event the joints of the pipts should start and causeleakage of the brine. The conduits a a rise at the sides of vat A, and have swiveled thereto the vat-pipe b, which, as shown7 is bent in simple coil and sustained at b in bearings on the vat. The swivel or union joint between the vatvpipe b and conduits ca may be of any convenient and well-known form-such, for example, as that shown in Fig. 3, where the cap-piece bl of vat-pipe b is ground true and snugly seated within the union-piece b3. A nut, bt, threaded to the cap and union-pieces, may tightly force these together, or, by slightly loosening said nut with a wrench, allow said cap-piece and its attached vat-pipe to swivel or turn about its seat in ICO union-piece b3. A stem-valve, b5, regulates the flow of liquid passing in conduits a a and the vat-pipe b,- or, again, as shown in Fig. 4, the vat-pipe b and collar b may turn within the stufiingbox formed at end of the unionpiece bl, as well understood. In this latter form of swivel-joint the regulating-valve, instead of being in the union-piece, as in Fig. 3, may be located at some convenient point on the conduits aa. The vatepipe b, being swiveled as descijbed, may be lifted at any time entire] y free from the vat without risk of leakage or need of shutting off the circulating brine. A pulley, 3, rope 4, and catches 5 on the side of the vat enable the vat-pipe to be held in either elevated or submerged position, as required. By reason of the swivel-connection the pipe may be raised'and wiped clean at any time, and allows also for convenient access to the vat,without disconnecting any of the parts, when it is desired to enter the vat after the beer has been withdrawn. By reason of its simple coil the vat-pipe can be wiped with great facility, and because of its arrangement in horizontal plane becomes com- Y pletely submerged in the liquid, and near the surface thereof, thus utilizing its entire cooling iniiuenee at the most eiif'ective situation. The coil of the vat-pipe, being wholly at one side of its axis, is raised clear from the liquid, so that no further effect is produced upon the liquid by the continued circulation of the cooling medium.

I ani well aware that it has heretofore been proposed to combine with the stationary supply and return cooling-pipes a vatconduit swiveled thereto and capable of being submerged in the liquid near the top of the vat.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the vat, and with the stationary supply and 'return conduits, of the vat-pipe swiveling about said conduits, said Vat-pipe being bent in horizontal coil, and arranged at one side of the axial line of the swivel and near the top of the vat, substantially as described.

2. The combination, with ene'vat, and with the stationary supply and return conduits for the circulating brine, of the vat-pipe swiveled to said conduits, and arranged in simple horizontal coil near the top of the vat, said vatpipe being provided with cord and catches,

substantially as described, for holding it in raised or lowered position relatively to the vat, substantially as set forth.

3. The combination, with the vat, and with the stationary supply and return pipes for the cooling agent, of the vat-pipe swiveled thereto and sustained in bearings on the vat, substantially as described.

In testimony whereof, witness my hand this 9th day of July, 1884.

DAVID BOYLE.
